Background

The return vehicle is a common toy, converts kinetic energy generated by pulling hands into elastic potential energy through a shaft and wheels arranged on the return vehicle, and generates the kinetic energy through the natural elimination process of the elastic potential energy, so that the return vehicle moves.

For example, in the most common return vehicle, a shaft connected with a rear tire is fixedly connected with a gear in a return gear, when a hand applies work (drags) to the vehicle backwards, the rear wheel rotates backwards, the force is transmitted to the return gear through the shaft to apply work, and the gear drives a return gear structure (a spring structure or a rubber band structure) to convert kinetic energy applied by the hand into potential energy (such as rotation elongation of a rubber band or compression of the spring and the like); when the hand is released, the vehicle loses a force for keeping the balance of the vehicle, namely, the friction force between the rear tire and the ground is increased (namely, the grip force in F1) when the vehicle is pressed by the hand, the return gear reversely releases potential energy through the shaft to do work, and then the shaft rotates to convert the potential energy into kinetic energy.

However, the return vehicle in the prior art can only move forwards and does not have a steering or other richer driving path. Therefore, the interest is remarkably reduced.

At present, most of toys with more abundant running paths such as steering toys in the prior art need to be provided with a motor and a speed change gear, the speed change gear is driven by the motor, and the angle of two front wheels is changed, so that the toy car can rotate.

More preferably, the housing is a vehicle shell.

In the present invention, the magnet/iron block on the swing arm and the magnet/iron block in the mounting cylinder are magnetically operated to control the swing arm. It will therefore be appreciated that there must be one magnet and that another matching configuration may be a magnet or an iron block. At the same time it should also be immediately possible here to perform the swinging of the oscillating arms both with mutual attraction forces and with repulsion forces between the magnets.

By adopting the technical scheme disclosed by the invention, the control and arrangement of different directions of the front, the rear, the left and the right of the programmed force returning vehicle can be realized without a motor and an electronic control mechanism. And the forward, backward, left turn, right turn and straight line can be combined to form different path arrangement modes. The product is low in cost, does not need a battery, is energy-saving and environment-friendly, and is more suitable for young children compared with high-speed driving driven by the battery.

More preferably, the housing is a vehicle shell 1.

We now describe the programming process in the present invention with reference to fig. 4, 6 and 7 in particular:

as shown in fig. 4, this is the outer side of the base 17 of the programming return car, and we see that two rows of sliding grooves are arranged on the programming operation position for controlling forward and backward movement, and a toggle handle 93 for controlling forward and backward movement is arranged in the sliding groove 612; the programming operation position for controlling the left turning, the right turning and the straight running of the trolley is positioned at the lower part, and a toggle handle 253 for controlling the steering is arranged in the sliding groove 611.

We see that in the illustration we also print five numbers, 1, 2, 3, 4, 5 respectively, at the bottom of the car, representing five programmed positions for the car to travel. Then, left-turn and right-turn arrows are printed and engraved at the lower operation site, and the steering wheel indicates that the position is the direction control. The upper operating position is indicated by up and down arrows to indicate forward or reverse.

We next see fig. 6 and 7. First, fig. 6 illustrates the forward/reverse control side. When the swing arm 351 passes the magnets 8 in sequence, the magnets mounted in the swing arm and the magnets below act differently according to the distance. For example, as shown in fig. 6, in the second position it is attracted, causing the front and rear rail sliding fixed shaft to rotate with the raised rib circular sleeve outside, and through a series of actions, the vehicle is moved backward by the front and rear shift spur 14 being reversed.

We then turn to the schematic in fig. 7, which is a schematic view of the straight, left turn, right turn side of the cart. As shown in the figure, all the

parts

1, 3, 4 and 5 are straight walking positions, and at the position 2, the swing rod swings, so that the swing rod deflects, the head of the trolley rotates left, and the trolley rotates left.

Referring to fig. 6 and 7, in the first step, the trolley moves forwards and straightly, then the second step moves backwards, and a left turn occurs simultaneously, and the third step, the fourth step and the fifth step all move forwards and straightly.

In addition, it can be seen that in this embodiment we do not enclose the casing on the top, where the decorative casing that does not pass can be enclosed as desired, thus obtaining the final product. Since the manners of sealing the upper housing and fixing the bottom housing are prior art, they are not described again.

What has been described above is a specific embodiment of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and such improvements and modifications are also considered to be within the scope of the present invention.
